Software
In what follows a number of software packages are listed, which I use in the course of data reduction and image processing for variety of goals. The specific application of individual software solutions is also 'a matter of taste'. I've got used to a certain procedure, which from my personal point of view provides the fastest way to my goal. A bit more complicated though is the accomplishment of the overlays, and I recommend reading the article that I published in Sterne & Weltraum 7, 2020 (in German).
